Laptop Turns Itself Off

Why is this happening? it suddenly goes blank black screen then blue and says please wait, then goes right back to the start so I have to sign in and start all over again, its been doing this for about two weeks and I can't work out why. My laptop is an hp.

My old HP did this shortly before it deceased itself rather spectacularly, so I'd advise you to back up all your stuff onto an external drive. xx

If you are on W10 it is probably attempting to update, which is very intrusive. I can't get updates because apparently I haven't enough storage space. Suits me down to the ground.

Some possible causes that come to mind:

1. Overheating due to blocked vents:
(Solution: Check that all ventilation points are unobstructed. Clean dust & fluff out).

2. Overheating due to a poorly mounted processor:
The processor in your laptop should be mounted onto a special thermal bonding paste, which transfers heat away from it. A knock to the laptop can cause the thermal bond to break, leaving the processor overheating.
(Solution: Not as easy as above because it needs someone to open up the laptop and check whether the processor is properly mounted).

3. Malware causing a system conflict:
(Solution: Download, install and run AdwCleaner: https://www.malwarebytes.com/adwcleaner )

4. A corrupt registry entry:
(1st try solution: Download and install CCleaner. Run it, click on 'Registry' and allow the program to tidy up the registry.
2nd try solution: Run System Restore, to take the laptop's registry back to a date before the problem first occurred. You can find it via Start > All Programs > Accessories > System Tools).

Thanks for that, I will show your answers to my Grandson and let him try to sort it for me as I am clueless, the lap top is only a year old so not on its last legs yet I hope.
